Can anyone please help shed some light on my new problem with Tailscale on my Flint2 router failing to connect after a successful initial setup but then getting stuck on "Connecting..." after any router reboot? I have tried all that I could think of with different fresh and clean firmware versions installs including various pre-4.7.0 ones as well as the two Op24 versions available in addition to doing a debrick install via uboot to no avail. I have even tried updating tailscale to the latest version using the tailscale update script with the same problem persisting. I really need Tailscale to work and would grateful for any advice to try and solve this.
Right, just noticed that Tailscale will connect fine after a reboot if my DNS server settings on the Flint2 are set to automatic and when I turn NextDNS off. This is strange as it was working perfectly fine with NextDNS enabled a couple of weeks back. What am I doing wrong here?
Ok I think that I might have found that the problem was possibly with NextDNS blocking "controlplane.tailscale.com". This is a bit strange as I have not changed by block list on it recently and it was working perfectly fine with Tailscale until recently. Anyway, I will leave this here in case someone else comes across the same issue.
